mongodb - How to get exact document result from key value type of embedded documents -


let have kind of document structured, attributes field embedded document , i've indexed attributes.key , attributes.value

1------------------------------------------------------------------------------------- {    "_id" : objectid( "5191d8e5d00560402e000001" ),   "attributes" : [    { "key" : "pobox","value" : "qakuwo" },    { "key" : "city", "value" : "cbdrip" },    { "key" : "address","value" : "zmycaa" } ],   "email" : "fwaudl_2@email.com",   "firstname" : "fwaudl_2"  } 2------------------------------------------------------------------------------------- {    "_id" : objectid( "5191d8e7d00560402e000055" ),   "attributes" : [      { "key" : "pobox", "value" : "snfriy" },      { "key" : "city", "value" : "jpdvri" },      { "key" : "address", "value" : "pholuw" } ],   "email" : "hqynwh_86@email.com",   "firstname" : "hqynwh_86"  }

my problem how exact document when querying based on attributes field,

db.app.find({ attributes.key:address , attributes.value:/.*uw.*/i })

the query result not expected, should result 2nd document without 1st document. know put regex on attributes.value, expecting check attributes.key have address value.

and if want filter key, such like,

db.app.find({ attributes.key:address , attributes.value:/.*uw.*/i , attributes.key:city , attributes.value:/.*ri.*/i })

any opinion helpful guys. thx.

just investigated little , figured out following. following uses index mentioned below. can explain() on find() check more index usage details

db.testing.getindexkeys() [ { "_id" : 1 }, { "attributes.key" : 1, "attributes.value" : 1 } ]  test:mongo > db.testing.find({$and : [ { attributes : {$elemmatch : {key : 'address', value : /.*uw.*/i }} }, { attributes : {$elemmatch : {key : 'city', value : /.*ri.*/i }} }] }).pretty() {     "_id" : objectid("5191d8e7d00560402e000055"),     "attributes" : [         {             "key" : "pobox",             "value" : "snfriy"         },         {             "key" : "city",             "value" : "jpdvri"         },         {             "key" : "address",             "value" : "pholuw"         }     ],     "email" : "hqynwh_86@email.com",     "firstname" : "hqynwh_86" }

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
